Creativity is increasingly essential, especially as automation and artificial intelligence replace routine tasks. Previous work suggests that the physical environment, for example, room size and object presence, might influence our creativity. Virtual Reality (VR) enables working in any environment and thereby allows optimizing the environment to foster creativity. Previous research on creativity, however, did not systematically control room size and object presence. As their isolated effects are unclear, we explore the effects of room size and objects on creativity in VR. Participants completed an alternative uses task in small and large virtual rooms that were empty or filled with objects. We found that the presence of objects increases subjective creative performance but found no effects of room size or objects on objective creativity. We derive implications to enhance the subjective experience in creative VR workspaces and discuss that the effects of room size might be smaller than previously thought.
